Observation DM Core Components

[Mireille Louys]

Dear all,

The draft version posted *before* the meeting is on line
at the bottom of the Twiki page:

http://www.ivoa.net/cgi-bin/twiki/bin/view/IVOA/ObsDMCoreComponents

Note this document will be upgraded and revised during the week , but  
to answer the various comments I had, this will give you an indication  
on how far we are.

The implementation part especially specifies the Obscore table with  
the mandatory fields we have discussed.
Due to the TAP/ADQL implementation, the data model is implemented as a  
set of Utypes.
The structure is flat and would not allow the encapsulation of an STC  
Obsdata structure. STC elements are actually reused inside the model  
as types re-used by the ObsCore Model in the Characterisation subpart.

I also put my 3 viewgraphs on line as a reminder.
Thanks for giving your feedback.

Cheers, Mireille,
DM chair
